Excuse me, why does it smell of burnt when I use a hair dryer, is it dangerous?

The level of danger is not very high.

The hair dryer has a burning smell and should be a hair dryer.

Aging, the principle of hair dryer is to heat up the metal wire, and then put the hot air.

Blow it out. The burnt smell should be the aging of those plastics and glues that have been heated, and it is best to replace them with a new one, but in fact, the degree of danger is not very high.

Under normal circumstances, if there is wind passing through the heating wire, the heating wire will not be red, and if you see redness, the temperature of the air outlet is not low. The reason for this may be that the air inlet is blocked, or the motor is short of oil, etc., and the speed has slowed down. It is best to dispose of it in time to prevent overheating and causing the plastic to melt.

Reason: 1. The hair dryer is a little old, and the plastic glue of the metal wire inside is aging by heat.

2. The hair is curled in and burned.

There is not much danger. <>

Hair dryer: A hair dryer is a combination of a set of heating wires and a small fan. When the electricity is turned on, the heating wire will generate heat, and the air blown by the fan will pass through the heating wire and become hot air.

If only the small fan is rotating, and the heating wire is not hot, then only the wind is blowing out but not hot. Hair dryers are mainly used for hair drying and plastic surgery, but they can also be used for local drying, heating and physiotherapy in laboratories, physiotherapy rooms, industrial production, art and other aspects.

It should be that your hair dryer is aging, and the principle of the hair dryer is to heat the metal wire, and then blow the hot air out. The burnt smell should be those plastics and glues that have been aged by heat, and it is best to replace them with a new one. But in fact, the level of danger is not very high.

Hair dryers require a lot of attention.

1. There is a burning smell, and you need to determine whether it is the smell from inside the hair dryer or the thing being blown.

2. If it is said that it is inside the hair dryer, it means that the quality of the hair dryer is not very good, it is recommended to pay more attention to it in use, and do not use it for a long time. Or eliminate it.

The hair dryer inside the 、、、 may have gotten dust, or some *** substance or something like that (unexplained).

Of course, it is also possible that your hair is scorched, but you don't see it, and the hair is dry、、、 don't use a hair dryer in the future, hurt your hair, it will split ends and lack nutrients.

If the hair dryer suddenly stops blowing and there is a burning smell, it may be that the internal temperature of the hair dryer is too high and it has entered the high temperature protection mode.

It may also be caused by the burning of the wiring, the internal being burned due to short circuit or high temperature, and the burning smell of the plastic after melting, which needs to be repaired by a professional institution.

Precautions for the use of hair dryers.

1. Turn on the power first and then turn on the switch. The advantage of this is that it can delay the service life of the motor and avoid damage to the motor due to sudden high temperatures. If you don't use it for a while, you should turn off the switch temporarily.

2. It must be gently held and put away, and do not keep shaking at will. Don't change gears too often, and the hair dryer should not be too close to your hair, and you should not blow straight in one place. Also do not blow on your hair or scalp to avoid unnecessary danger.

There is also a voltage that should be kept in a steady state.

3. In the process of using the hair dryer, if there is an abnormal phenomenon, such as smelling peculiar smell, hearing noise, suddenly not working, etc., the switch should be turned off in time, the power supply should be cut off, the cause should be identified, and the maintenance should be normal before use.

4. Do not use a hair dryer in the bathroom and where there is a water source, and do not use a hair dryer in high temperatures and places with flammable materials. The time of using the hair dryer should not be too long, so as not to affect the service life of the motor due to the high temperature.

5. If the hair dryer has not been used for a long time, when you take it out and use it again, it is best to turn on the electricity for a while to remove moisture, and you need to check the normal operation before using it.

Caused by too high temperature, your hair dryer overheating protection switch is broken, the temperature is too high can not be powered off, the burnt smell is the plastic smell of the wind blowing at too high temperature, if it can be used normally after cooling, it is necessary to pay attention to the temperature in the next use, and the hot air will be used for a while to turn on the cold air.

If the heating wire is still hot, it will smell burnt, and the motor will not rotate, it may be that the motor is stuck, or the rectifier diode is burned.

Blowing with hot air for too long, the plastic in front of the hair dryer melts, and the quality is a problem! I've blown a few of them.

"No wind" means that there is a problem with the power supply circuit of the hair dryer motor or the motor itself, you can turn on the hair dryer to see if the contact of the heating wire in a small section of the electric wire that provides voltage for the motor is good, and whether there is a problem with the rectifier circuit connected to the two electrodes of the motor, if there is no problem with these, the motor is faulty and needs to be replaced.

The switch melts with overheat, and the switch is replaced.

Because the hot air blown out of the hair dryer is generated by the heating wire at the front end, if the heating time is too long, the plastic material at the front end of the hair dryer will be burned, so it is normal to have a burning smell, especially if the hair dryer you just bought will have a burning smell. So don't use the hair dryer for a long time when using it.

The heavier the hair dryer, the better the quality, the wall thickness, strong, heat resistant, double insulation, some have an ionizer inside, which can produce ionized wind, make the hair soft, and the ionic wind also has the ability to sterilize.

However, no matter what kind of hair dryer it is, it should not be used in the bathroom, and there is a great risk of electric shock in a humid environment after bathing.

Answer 2: If it is the burnt smell of the hair, then it is because it is easy to suck the short hair into it when the hair dryer is running, and when the hair sucked in is wrapped around the heating wire in front, it will emit a burnt smell, so you don't have to worry about it, the hair inside will fall off by itself after a long time.

In addition, when the hair dryer is in use, it is necessary to pay attention to the operation of the small fan inside, if the air output of the normal gear is very small, the motor is entangled in hair, so that the heat of the heating wire in front of it cannot be dissipated, the temperature will be higher and higher, and it is easy to burn people and even **.

The "burning smell" of the hair dryer is mainly caused by the short circuit of the heating wire inside the thing that has been used for too long, which increases the heating power and the internal temperature is too high.

1. If it is the burnt smell of plastic, then it is possible that the internal wires are burned, and there will be a burning smell.
